I have Bosch WFVC8440UC/19 washing machine. There seems to be a leak in the tub above the drive motor where the company filled a seam/gap with some sort of black glue. Is this seam standard on tubes?

I will try and help with this problem about Bosch WFVC8440UC/19 Washing Machine,
Hi Tom,
You might need more information about this Bosch washing machine. Below, you will find the exploded diagram of the model and all the associated parts. The drum appears to be made of separate components, but you will notice a dotted line around all the drum parts, labelled as 0311.
Sometimes, the manufacturer may have installed a sealed drum in the machine. This means the two halves of the drum are welded together. Manufacturers do this to make repairs harder, which encourages buying new machines instead of fixing old ones. If the seal on the drum (labelled 0316) is leaking and the drum is welded or glued, you won’t be able to access it.
You should inspect the drum all around to see if there are drum bolts (labelled 0315) fitted. These bolts usually number 10-12 and join the two halves of the drum. I have made a video showing how to dismantle these machines, but if your drum is welded, you’ll need to replace it entirely.
One possible solution is plastic welding where the water is leaking, but I would need pictures to give better advice. Another place it might be leaking from is the heating system (labelled 0331). Sometimes, heaters become loose and drip water onto the motor.
Also, check the top of the machine for any loose hoses connected to the drum from the soap box. Sometimes water trickles down from these hoses and looks like it’s leaking from the drum when it isn’t.
I hope this diagram helps you.
